The app is now available for free download at the BlackBerry World store. The app does give Z10 owners an open alternative to the BlackBerry Messenger service.

Martyn Mallick, Vice President of Global Alliances and Business Development at BlackBerry said "WhatsApp is a leading mobile messaging app that connects people to their contacts on several platforms, and we are pleased to work with WhatsApp to bring their service to our customers".

WhatsApp will come with real-time push notifications, which can be displayed, even when the device is not unlocked.

Whatsapp will come fully integrated with BlackBerry contacts. Meaning, when the user launches the app for the first time, it will automatically scan the contact directory and extract contacts.
